Taken from the tales of King Aurther and his knight, Percival, this refers to a person or couple who is searching for the "holy grail", the "unicorn", the HBB.

Percival did locate the Grail at one time, but, being too immature and failing to ask the proper question, he failed in attaining the Grail and he must grow spiritually and mentally before he could locate it again.

Percival is described in some places as "the least worldly and the least groomed of all the knights", having been raised in the woods away from society, and "extremely pious but somewhat naive".

This is analogous to a couple who is new to polyamory and, lacking sufficient role models in alternative relationships and lacking the experience themselves to understand the complex nature of multi-partner relationships, the couple believes, rather naively, that the way to circumvent jealousy, possession, or feeling "left out", is to find one person to share equally.

The rationale is that one partner cannot get jealous if he or she gets to do all the same things at the same time with the new partner as the existing partner. This does not refer to triads that just happen to spring up because the relationship between all involved was most compatible in a triad relationship. This is specifically for existing dyads seeking the Hot Bi Babe to "complete" their family and perhaps solve any underlying issues along the way.

That skeevy couple over there hitting on all the young females trying to find a Hot Bi Babe for their threesome is just Percivalian

To prescript a relationship, then, is to create a set of rules governing the relationship before the people involved ever get into said relationship. These rules are often set up to define a relationship involving someone who is not even in existence yet and therefore cannot give his or her input into the relationship agreements, such as a married couple deciding the rules for a future extramarital partner before even finding one.

By contrast, a descriptive relationship describes the relationship as it is at the time with input from all involved.

Even though John and Mary haven't met anyone they're interested in yet, they have decided beforehand that anyone they date will be female, in love with them both equally, single, will live no more than 10 miles away, will not call John by the nickname "bunnylips", will not eat with them at their favorite restaurant, and cannot ever listen to the song John and Mary danced to at their wedding while John and/or Mary are in the room with her. When they meet her, these rules are non-negotiable and she has no say in them. They prescripted their relationship.

The slang term for a chain of fast-food restaurants called Chik-Fil-A. Usually used in a derogatory term to refer to their strongly Christian policies (being closed on Sundays explicitly for their employees to attend church), anti-gay policies and extremely large financial contributions to anti-gay-rights bills and amendments, both of which stem from the owners' interpretations of their denomination of the Christian bible.
